Abstract: Methods for identifying encrypted content in ones of a plurality of encrypted data files in a library of encrypted files without decrypting the data files utilize crowd sourcing for content identification. A method includes selecting, by a computer, content titles for presenting with ones of identifiers for the data files in a data structure. Each of the identifiers includes a hash of metadata for one of the data files and the content titles include a character string that identifies each file's content. The user selection data identifies the content titles that correspond to the data files. The computer determines which content titles satisfy a minimum confidence threshold for associating with one of the identifiers, based on a quality or quantity of the multiple independent clients supplying the user selection data. An apparatus for performing the method includes a memory holding instructions for performing steps of the method as summarized above.

Abstract: Methods for identifying content in encrypted or otherwise protected files utilize crowd sourcing for content identification. One such method includes, using a computer, selecting defined content titles to be presented with identifiers for data files for use in obtaining user selection data. The method may also include receiving the user selection data from multiple independent sources, the user selection data indicating users' selections of single ones of the content titles for respective single ones of the data files. The method may also include determining for ones of the identifiers, using the one or more computers processing the user selection data, respective ones of the content titles satisfying a minimum confidence threshold for association with the ones of the identifiers. An apparatus for performing the method comprises a processor coupled to a memory, the memory holding instructions for performing steps of the method as summarized above.
